mac won't work can you fix that?
Give it a shot now.
If it still doesn't work, I'll need more details about what the issue was, because I have it running on my MacBook Pro.
Are you on Big Sur by any chance? It seems to be causing issues with the .app files that Unity builds.
One fix to try is running something like this in a terminal:
sudo chmod -R 755 'PathToAppFile.app'
That will set permissions to let you run the app as an executable, which solves one of the potential issue you might be hitting.
Then you might still have the usual Gatekeeper warning about not running apps by unknown developers (i.e. me). You can sidestep that by going to System Preferences > Security & Privacy, and clicking the Open Anyway button on the General tab. Alternatively, you can disable Gatekeeper altogether, but I'll leave you to figure that one out.
